There is nothing more synonymous with the male wardrobe than the suit, an item of clothing that almost every man of style and substance has sported since it was invented some 150 years ago. A list of every guy who has worn a suit well would be impractically long - and, incidentally, so would a list of everyone who has worn a one badly - so instead we have selected six men who we consider to be iconic suit wearers, from Mr Fred Astaire in the 1950s to Mr George Clooney today. The thing about the suit is that it is timelessly stylish, meaning the image of a sharply suited actor or president from more than half a century ago can still inspire us today.
